Highlights of Solar and Geomagnetic Activity 26 May - 01 June 2014
Solar activity was predominately low with very low levels observed on 30 May. Region 2065 (S19, L=150, class/area Dai/180 on 25 May) produced a majority of the activity including the period's largest event, a C4 X-ray event at 27/1415 UTC. Regions 2071 (S12, L=080, class/area Dac/150 on 21 May), 2076 (S19, L=051, class/area Dao/050 on 28 May) and 2077 (S06, L=300, class/area Dai/110 on 01
Jun) all produced low-level C-class activity through the period. On 01 Jun at 0137 UTC, Region 2079 (N12, L=282, class/area Hsx/120 on 01 Jun) produced a C2/Sf X-ray event near the NE limb with a pair of closely spaced Type II radio sweeps associated with the event.
Estimated shock velocities were recorded at 1015 and 892 km/s. No Earth-directed CMEs were observed during the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels on 26 and 27 May and at normal levels the remainder of the period.
Geomagnetic field activity was predominately quiet through the period. Isolated unsettled periods were observed midday on 29 May and isolated active periods late on 30 May, both instances due to prolonged periods of southward Bz.
Solar wind speeds, measured at the ACE spacecraft, began the period at about 400 km/s and gradually declined to near 325 km/s by 29 May. Wind speeds remained steady between 325 to 340 km/s through midday on 31 May where a further decline to end-of-period speeds of about 290 km/s were observed. Bt generally ranged from 2 to 5 nT with a period of 6 to 11 nT observed from midday on 30 May to early on 01 Jun. The Bz component followed a similar pattern with weak variability between +/- 3 nT through a majority of the period. However, from about 29/0830 UTC to about 01/0100 UTC, Bz varied between +9 to -10 nT. The phi component was in a mostly positive (away) sector through the summary period. A negative (towards) orientation was observed from 26/0000 UTC - 28/0100 UTC and again from 29/0600 UTC - 30/1300 UTC.
Forecast of Solar and Geomagnetic Activity 02 June - 28 June 2014
Solar activity is expected to be at low levels with a slight chance for moderate activity after 08 Jun with the return of old Region 2065 (S19, L=151).
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal levels for most of the period with moderate conditions possible from 08 - 12 Jun and again from 21 - 23 Jun.
Geomagnetic field activity is expected to be at quiet to unsettled levels on 03 - 04 Jun, 06 - 08 Jun (with isolated active intervals on 07 Jun), 18 - 19 Jun, 25 - 26 Jun and finally on 28 Jun, all due to recurrent coronal hole high speed streams. Quiet conditions are expected for the remaining days of the forecast period.
